4.1.4 Trial Operation for Servomotor with Brakes
Holding brake operation of the servomotor can be controlled with the brake interlock output (/BK) signal of the servo drive.
When checking the brake operation,take advance measures to prevent vibration due to gravity acting on the machine or
external forces. Check the servomotor operation and holding brake operation with the servomotor separated from the
machine. If both operations are correct, connect the servomotor to the machine and perform trial operation.
Refer to 4.3.4 Setting for Holding Brakes for wiring on a servomotor with brakes and parameter settings.
4.1.5 Position Control by Host Controller
As described above, be sure to separate the servomotor and machine before performing trial operation of the servomotor
without a load. Refer to the following table, and check the servomotor operation and specifications in advance.

JOG Operation
(Constant speed reference
input from host controller)
Servomotor speed Check servomotor speed as
follows:
·Use the servomotor speed monitor
(Un000) on the panel operator.
·Run the servomotor at a low
speed.
For example, input a reference
speed of 60rpm, and check to see if
the servomotor makes one
revolution per second.
Check the parameter setting at
Pn300 to see if reference
speed gain is correct.
Simple positioning Number of
servomotor
rotation
Input a reference equivalent to one
servomotor rotation, and visually
check to see if the shaft makes one
revolution.
Check the parameter setting at
Pn200 to see if the number of
PG dividing pulses is correct.
Overtravel (P-OT and
N-OT Used)
Whether the
servomotor stops
rotating when
P-OT and
N-OT signals
are input.
Check to see if the servomotor
stops when P-OT and N-OT signals
are input during continuous
servomotor operation.
Review P-OT and N-OT wiring
if the servomotor does not
stop.
4.2 Control Mode Selection
The control modes supported by the ProNet series servo drives are described below.
